Intermolecular forces are forces of attraction between molecules. These forces influence properties of substances such as boiling and melting points, phases at room temperature, viscosity and many more.

Intermolecular forces can be divided into 4 major categories:

1. ION-ION

This is the strongest intermolecular force. It is present in all ionic compounds. To recognize it, look at the formula and see if it has metal with a...

Which of the following substrates would react most efficiently in a substitution reaction with sodium cyanide (NaCN)?

(A) 1-iodohexane
(B) 1-fluorohexane
(C) (R)-2-bromohexane
(D) chlorocyclohexane
(E) 1-bromo-1-methylcyclohexane

Answer: (A) 1-iodohexaneA

Solution:

We first must figure out which reaction does the question ask about. The question mentions substitution reaction, thus either SN1 or SN2. We are also given NaCN...
